Hello, I've just published my obfuscation plugin, Hikari Email & URL Obfuscator.
It filters posts, comments and text widgets to obfuscate all found links.
The plugin main page is http://Hikari.ws/email-url-obfuscator/ soon I'm gonna publish an article with advanced usage tutorial and another article with a lot of exemples and tests.
I'd like to hear what people think of it and ideas to make CSS reversion work without breaking XHTML validation. :)
